To all whom it may concern:

Be it known that I, PETER CnnrsJAN JEP- PESEN, manufacturer, subject ofDenmark, residing at No. 36 Oesterbrogade, Copenhagen, Denmark, haveinvented new and useful Improvements in and Relating to the Constructionof Cycles and the Like, of which the following is a specification.

This invention relates to a safety device for cycles and the like andconsists in the branches of the front fork being connected together bymeans of a fitting which in its turn is connected to the handle bar orto the steering tube, by means of a rod carried through the tube of thefront frame. The fitting in question, as well as the rod in question,are made of soft and tough iron or the like, and are intended to keeptogether the parts of the front fork in the event of the same breakingat the crown. The rider is then able to jump off from the cycle withoutfalling, as the cycle cannot collapse suddenly. This device is,therefore, intended to prevent accidents due to a breakage of the frontl fork or of the handle bar.

Two constructions according to this invention are illustrated by way ofexample in the accompanying drawings.

Figures 1 and 2 show the device for connecting the above mentionedfitting with the handle bar or with the steering tube, partlyin section.Fig. 3 is a section on line A-B of Fig. 1.

In the construction shown in Figs. 1 and 3, c is the outside frame tubeof the front frame, in whichat the tcp and at the bottom are providedball bearings b and c, for the tube f of the front fork d. The handlebar g is provided with a short tube 7i introduced into the tube f andcapable of being locked by means of a clamping ring 7c mounted on theportion of the tube f slit at the top. At the top, namely, below thecrown m, is mounted a plate u provided with claws p which surroundentirely or even partly the fork branches d, and to the said plate issecured a tube g projecting upward into the tube f and fitting thelatter exactly. The plate n is provided in the center with a thickenedportion or boss r which is perforated and provided with screwthreads fora rod s extending through the tubes f and 71, and the handle bar g, andprovided with a head t.

When it is desired to adjust the handlebar g at different height thanbefore, the clamping ring 7c is loosened, and the handlebar is pulledupward or pushed down, whereupon the clamping ring 7 is again tightened.The length of the rod s is adjusted to suit the height of the handlebarby screwing it by means of the head t into the part of boss r to agreater or less extent.

ln the construction shown in Fig. 2, the fitting n together with theclaws p, instead of being connected to the handlebar, is connected tothe front tube f. The rod s1 is provided at the top with a thin cone uprojecting with its downward pointed end into a piece of tube o slottedand mounted loosely in the tube f. The rod 81 is provided at the bottomwith screwthreads for a'nut t1 and prevented in a suitable manner fromturning, for instance by being provided with a fiattened surface andguided by means of a corresponding hole in the fitting n.

Vihen the nut t1 is tightened, the cone u penetrates into the tube owhich is thus eX- panded and gets jammed in the front tube in that waythe tube is connected to the fitting n and to the claws p.

Having now particularly described and ascertained the natureof my saidinvention and in what manner the same is to be performed, declare thatwhat I claim is 1. ln a safety device for cycles consisting incombination of a rod'passing through the steering tube, a means forconnecting said rod to the handle bar, a plate bridging `the front fork,a pair of claws attached to said plate adapted to engage the front forkmembers, a means for adjusting said rod to elevate or depress the handlebar substantially as specified.

2. In a safety device for cycles consisting in combination of a rodpassing throughthe steering tube, a means for securing said rod to thehandle bar and tothe bridge of the front fork, a plate attached beneaththe bridge of the front fork, said plate being provided with athreadedopening, a claw on each end of said plate to engage a forkinember and adapted to reinforce the bridge of said fork, and a means ofsecuring said plate to the steering tube and ay means of adjustment forsaid handle bar substantially as specified.

3. In a safety device for cycles consisting in combination of a rod inthe vsteering tube adjustably connected, a reinforcing plate securedbeneath the bridge of said fork provided with a pair of claws to engagethe fork members, said plate being furthermore provided With @threaded oenng to engage with ln test'rnony whereof I have signed my stud rod, anut on the ovver end of stud 1 od name to tl1 1s speoicaton in thepresence of l0 and a cone on the other end 1n the Steerlng twosubsorlblng Witnesses.
